Dissolution kinetics of chromite overburden by using mineral acids
Gautam Roy Chaudhury,P. K. Swain,L. B. Sukla 한국화학공학회 2007 Korean Journal of Chemical Engineering Vol.24 No.6
different mineral acids were used to determine the kinetics of dissolution of Ni and Fe from chromiteas acid concentration, pulp density, temperature and particlesize. Both Fe and Ni dissolution followed 1st order irreversible kinetics. The activation energy was also measured. Uni-fied rate equations were established for Ni and Fe dissolution for two different mineral acids, HCl and H2SO4. The dis-solution reaction was observed to follow diffusion control-dense-constant size spherical particles.
